Use thin flat blade screw driver to separate the case, starting at the bottom edge and work your way around. The monitor is held together with plastic finger hooks, easy to snap together but hard to separate, you will be breaking some of the fingers in the process. Basic LCD monitor and TV troubleshooting guide: Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed ACER monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

SOURCE: Acer AL1916W 19" LCD Monitor '' no power''
There was a busted fusible coil in series with the main line supply. Changed it with an ordinary fuse. There are available voltages for 5V and 12 volts but still there is no power indication on the panel and never turns on. I checked the backlight but no output power. the system control has power supply of 3.26 volts. What really the problem of this unit?
